RING SPINNING AND DOUBLING MACHINERY.

srncIFIcATioN' forming part of Letters Patent No. 614,831, dated November 29, 18 8. Application filed December-20, 1897- $erlal No. 662,714. (No model.)

To all whom it may concern:

Be it known that I, JAMES BUOKLEY, retired cotton-mill manager, a subject of the Queen of Great Britain and Ireland, residing at 51 Mount Pleasant, Liverpool, in the county of Lancaster, England, have invented Improvements in and Relating to Ring Spinning and Doubling Machinery, of which the following is a specification.

to My said invention relates to the rings and travelers of ring spinning and doubling machinery, and especially to the type of ringtraveler consisting of a curved bar with a fork at each end and sometimes known as a flier- 5 traveler, and in order to describe my inven tion more clearly and to render the same more easily understood I have attached hereto a sheet of explanatory drawings, to which I will refer. I In the said drawings, Figure 1 shows in elevation, on an enlarged scale of twice the ordinary size, a traveler made in accordance with my invention. Fig. 2 is a plan of Fig. 1. Fig. 3 represents in sectional elevation the form of ring which I use in conjunction with my improvedtraveler. Fig. 4: is a plan of the ring with the traveler in position therein.

When using double-fork travelers as at present constructed, it has been found in practice that the travelers have a great tendency to vibrate and shift their positions when running and to cant in the ring in such a manner that the lower member, and sometimes the upper member, of each forked end becomes worn and cut. The wearing of the traveler at the parts thus named is very rapid, as I found by experiment that such wearing or nicking is very perceptibly effected even in the time employed in the spinning of a single cop. This unsteadiness, canting, and wearing of the travelers not only militate against the production of perfect yarn, but also are the cause of such an amount of friction and drag that-breakages of the yarn are 5 frequent,besides absorbingpowerand quickly rendering the travelers useless. At present these travelers are made with the curved backbone or bar disposed equidistant between the members of the forks.

By careful experiment and repeated trials I have ascertained that the working of the traveler is very greatly improved by placing the said curved backbone below the center that is, toward the lower side of the traveler in the position it assumes when placed in the ring.

The improved construction or formation of traveler is shown in Figs. land 2, the dotted line, Fig. 1, indicating the center of the traveler-forks. This preponderance of weight upon the lower side has the effect of steadying the traveler and causing it to run without vibrating and canting, as at present experienced. Moreover, as will be noted from an inspection of the delivery end of the traveler, (marked 9%,) by placing the backbone below the center of the forks, as described, the yarn resting on the top of the backbone at this point is delivered to the cop from the center of the fork. This also materially assists in steadying the traveler and preventing it from canting.

The objectionable wearing and cutting of the traveler are obviated and the traveler runs swiftly and without any of the frictional drag heretofore experienced by the canting of the traveler, thus saving power, prolonging the life of the traveler, and producing better work.

By experiment I find that the wearing of my improved traveler by frictional contact with the ring occurs chiefly at the back of the curved backbone at the point marked a and upon the top of the lower forks marked 6. This will be more apparent from an inspection of Fig. 4. As the improved form of traveler does not cant and vibrate, but is maintained upright and steady, the curved backbone of the traveler, flying outward by centrifugal force, bears upon the interior suror face of the ring, and thus takes the frictional drag chiefly at that point. In conjunction with the said improved traveler I use a ring of the form shown in the sectional view Fig.

3. The ring a is formed on the interior pe- 5 riphery with a curved or rounded surface, as shown in the section. I

In combination with my improvedform of traveler I find that the said curved or rounded inner surface secures easy running and re 10o duced wear and drag, which materially advances the utility of my invention.

I am aware that rings with slightly-rounded interior peripheries have been before used, and I make no claim to such a ring per se, but only when used in combination with my improved traveler.

I have indicated in the sectional view Fig. 3 the extent of rounded surface which I have found to be most suitable for the purposes of my invention.

The interior surface of the ring is lubricated in any suitable or convenient manner. For instance, I might drill or otherwise form a small hole d in the thickness of the ring and conduct through the same a minute quantity of oil or other lubricant to insure the easy running of the traveler.

I declare that What I claim is-- In combination, the ring having a rounded 20 or convex inner periphery, the traveler having the U-shaped forks and having a curved backbone or bar located below the center of the forks, substantially as described.

In witness whereof I have hereunto set my 2 5
